Monster-Cropped Green Crack Clones

Day 49 in flower. This week I saw some bad nutrient burn/light stress so I moved my lights up and took a PPM measurement of my run off. It was going in at 300ppm and coming out at 1800ppm. So, I flushed with a little FloraKleen and a bunch of water to get the ppm back to an acceptable level. Will give only water again next time and then back to a feeding schedule for the last week or so. I also staked up some of the branches that were falling over and pulled all the dying/burned leaves.
